Serial No. 339,624 2 Claims. 184-43) This invention relates to improvements in tral bearing 11 and end bearings 12 secured to means for lubricating the working parts of the the housing 5. 13 designates connecting rods power end of a pump or similar apparatus, and mounted on the crank pins 14, said pins being it is particularly directed to means for conveyintegral with gear wheels 9. The other ends of ing or circulating the lubricant, said means asconnecting rods 13 are secured to cross-heads sociated with the gear drive mechanism of the 15, by means of cross-head pins 16.

The lubricant in the reservoir 19 will be teeth of one gear to the point of contact with ancarried upwardly in the troughs 20 by the rota- Othel e p Squeezing or l tt ng the tion of gear wheels 9.
